EN 1447:2009 (E) 4 Introduction This standard describes a method for determining the long-term resistance to internal pressure of glass-reinforced thermosetting plastics (GRP) pipes. It is a method which uses the following conditions: water as the reference liquid inside the test piece; water or air as the environment outside the test piece. The method can be used for tests at different temperatures. It should be noted that, for a given temperature, the results obtained can differ depending on the end loading conditions and whether the external environment is water or air. The method described in this standard differs from those in some other similar standards, in the following details: the failure criteria and the detection of failure; the strain in the longitudinal and circumferential directions may be measured during the test; the test pressure is maintained constant. This method may be used to obtain data to establish internal pressure versus time-to-failure relationships at different temperatures. The procedures for establishing the relationships are not within the scope of this standard. For such purposes attention is drawn to EN 705. SIST EN 1447:2009
